Chilas BT3 – 850 nm tunable laser
The Chilas BT3 is an 850 nm external cavity laser (ECL) in a standard 14-pin butterfly package, combining ultra-narrow linewidth performance with a tuning range larger than 30 nm. Designed for OEM integration, the BT3 is well suited for quantum optics, atom cooling, and spectroscopy applications requiring high-coherence near-infrared laser light.

Ordering Information
• Minimum order quantity: 10 units
Need fewer than 10? We understand that’s not always possible, get in touch and we’ll see what we can do.
• Looking for a complete laser module?
The CF3 is a bare component for OEM integration. If you need a ready-to-use module with electronics, software control, full connectivity, and no moving parts, you might want to take a look at our standard laser products:
→ ATLAS 1550 — C-band narrow linewidth tunable laser module
→ COMET — C-band swept source laser module
→ POLARIS — frequency-stabilized single-frequency laser module
